It's not too surprising to me, I use an MSI Wind as my primary computer -- I guess you could call my iPod touch my secondary computer

. All I did was upgrade the memory from 1GB to 2GB and upgrade the wireless card from 802.11g to 802.11a/g/n to better suit my hardware needs. I paid $375 after the Microsoft Live Search Discount for the machine itself.
But even with the 1.6GHz Atom processor, it serves all of my daily needs while running Windows XP Home SP3: Google Chrome/Firefox 3.0, Word 2007/Excel 2007, Photoshop CS3, and iTunes. I use other apps every once in a while, but these are the main ones I use.
Most of the time, my MSI Wind is sitting on my desk hooked up to my USB hub, 250GB external HDD, and 22" monitor. When it's not on my desk, the keyboard is a blast to use and the 10" LED-backlit display is gorgeous. I usually have a Bluetooth mouse with me for extended use away from my desk.
My only complaint: the 3-cell battery isn't enough; I'm waiting on MSI to release the 6-cell as a separate option.
I guess I've gotten to the point with computers where I don't care about outspec'ing the next person -- I just want something that works and is affordable.
